Barbier Color

For professional colorists

Your colour book, that also does the maths.

This is what it hands you.

Not advice and not a range: the bowls, the grams, the developer and the time. A formula you can take to the shelf and mix.

At level 8 the pigment exposed is yellow, and a violet base cancels it. The second tube sets the depth.

  • The code, big.It is what you look for on the shelf with your hands full.
  • Grams, not ratios.45 g of colour and 45 g of developer. No solving a 1:1 while standing at the scale.
  • Every bowl says why it is there.If you disagree with the reasoning, change the input and the formula rebuilds.
  • An engine, not a chat.It applies colour theory rules. It does not guess and it cannot invent chemistry.

And it tells you when not to.

The most valuable thing a colour tool can do is stop you in time.

Henna or metallic salts

The formula stays hidden until the incompatibility test comes back clean.

Henna and metallic salts react with peroxide: they can heat up suddenly, smoke and snap the hair. Strand test with 20 vol and a little ammonia, 30 minutes.

  • A block, not a banner.The formula is not shown. A red banner over a readable formula stops nobody.
  • And when there is no danger.The app being quiet is not a guarantee — it is the absence of a rule that applies.

When she comes back, you stop guessing.

Repeating a colour is not re-applying the same mix. Between visits the root grew out virgin, the grey advanced and the ends washed out. Barbier asks what changed and recalculates.

  • How much has the root grown out?Decides between a retouch and a retouch plus a lengths refresh.
  • Has she had anything done elsewhere?Box dye, bleaching, henna. The last one can block the service.
  • How much grey does she have today?Changes the natural base in the mix and the processing time.
  • How are the mids and ends?They decide whether a separate bowl goes on, with no cream developer over already-coloured hair.

Hair does not have one level either: when the root and the ends sit apart, the service splits into two bowls. That is exactly what prevents the band at the old regrowth line.

It speaks your shelf.

Twenty-four brands with their lines, their developers and their ratios. And if yours is missing, you add it in four fields — or photograph the tube.

Your client arrives with a formula from another salon. Barbier reads it and rewrites it in the brands you actually stock. No manufacturer will ever build this: it would send their colorist to a competitor's tube.

  • Your brands first.The ones you tick come first in every formula. The rest stay one tap away.
  • Your brand, even if it is not famous.Name, how it writes shades, its lines and its ratios. Only the name is required.
  • Read the tube, not a barcode.The code printed on the tube IS the colorimetry. The camera reads it on the phone and you decide what each line is.

No servers. No account. No signal.

Everything lives on your phone, which is why it works in a basement and why your clients' photos never leave it.

  • Works with no internet.The engine runs on the device. There is no cloud call to wait for.
  • Photos are never uploaded.There is nowhere to upload them to. We hold no copy of anything of yours.
  • Free to calculate.The subscription removes the limit on how many clients you keep. The ones you already saved stay yours.
